Which bacteria is MOST commonly isolated from infected diabetic foot ulcers in patients with no prior antibiotic exposure?
Answer: Staphylococcus aureus
Staphylococcus aureus is the most frequent causative organism in previously unexposed diabetic foot infections, though MRSA is common in healthcare-associated infections.
A wound culture is obtained by the Levine technique. This involves:
Answer: Rotating a swab with 10 seconds of pressure over 1 cm² of clean wound tissue
The Levine technique applies firm rotating pressure over a 1 cm² area of clean wound bed for 10 seconds to capture deeper wound tissue organisms rather than surface contaminants.
When documenting wound measurements, the MOST clinically consistent method for measuring wound length and width is:
Answer: Head-to-toe axis by side-to-side axis regardless of wound shape
Using a consistent head-to-toe by side-to-side orientation eliminates clinician variability and allows accurate serial comparisons over time.
A patient with a chronic venous leg ulcer has lipodermatosclerosis of the lower leg. This finding indicates:
Answer: Chronic venous hypertension causing fibrosis of subcutaneous tissue
Lipodermatosclerosis is induration and fibrosis of subcutaneous tissue caused by chronic venous hypertension and resulting hemosiderin deposition.
Which factor in the local wound environment MOST directly impairs oxygen delivery to healing tissue?
Answer: Wound edema increasing interstitial fluid pressure
Edema raises interstitial fluid pressure, compressing capillaries and increasing the diffusion distance for oxygen from vessels to cells.
A wound care specialist documents 'epithelialization at 30% of wound surface.' This finding indicates the wound is in which phase of healing?
Answer: Proliferative phase
Epithelialization occurs during the proliferative phase, alongside granulation tissue formation, as keratinocytes migrate across the wound surface.
Which seating surface characteristic is MOST important when selecting a wheelchair cushion to prevent ischial pressure injuries?
Answer: Pressure redistribution capacity confirmed by pressure mapping
Pressure mapping objectively quantifies interface pressure at bony prominences, allowing clinicians to select and fit cushions that achieve optimal pressure redistribution.
